APPLIANCE FOR USE IN HAIR WAVING Filed Aug. 25, 1931 i Fig.1. 49 16 24fj 25 19 j Patented Feb. 23, 1932 UNETED STATES PATENT QFFICE APPLIANCEFOR USE IN HAIR WAVING- Application filed August 25, 1931, Serial No.559,305, and in Great Britain August 30, 1930.

This invention relates to apparatus for use in hair-waving appliances ofthe type wherein steam is injected into tubes or ackets therebysubjecting the hair, which has been previously wound onto curlers andplaced inside of the jackets, to a moist heat and steam treatment.

The invention is more particularly concerned with apparatus of the abovetype in which a plurality of steam boilers is provided, one for eachhair waving appliance, and an object of the present invention is toprovide an improved supporting device for the boil ers whereby fillingof the boiler is facilitated and in a manner which avoids spilling oroverflowing of the water.

According to the invention the support for a series of boilers of thetype referred to comprises a tray or container which is provided with agutter or the like for collecting overflow of water or the like andcarry ing it to waste.

Further features of the invention will be hereinafter described anddefined in the claims. 7

In the accompanying drawings Figure 1 is an elevation partly in sectionof a supporting tray according to the invention.

Figure 2 is a half plan of the tray or container.

The invention will be described in connection with steam boilers asshown and claimed in our British patent application No. 25,987

The boilers (only one of which is shown) 3 are arranged in a circularseries and are provided with a valve device 4, a heater 5, a down-takeconnection 6, a filling aperture 7 and a safety valve connection 8.

In carrying the invention into effect a boiler supporting tray orcontainer 9 is provided which is carried by a hollow standard 10 havingtelescoping tubes whereby the height may be adjusted, the lower tube 11having feet 12 provided with casters.

The tray may be of any suitable shape in plan, and in the form shown iscircular, the boilers being arranged adjacent the circumferential wall13. An annular gutter or drain 14 is providedwhich is connected with adowntake tube 15, the lower end of which projects into the standard 10,whereby any liquid collecting in the gutter is led away to a wastevessel 16 suitably clipped to the 55 feet 12. The gutter 14 may be ofany suitable shape .in cross-section, square, semicircular or theSimilarly, any water of condensation resulting from steam escaping fromthe boilers when first boiling up with open valve will be collected andcarried away.

The base and wall of the tray are pro- 5 vided with apertures 17 and 18respectively to accommodate the downtake tube 6 and valve 4. The holes18 may be replaced bynpwardly extending slots but it is preferred thatthe rim 19 shall be complete for the purpose of making the wall 13rigid.

The tray is connected to the standard 10 by a nut 20 and screwed cap 21which latter is threaded to receive a bolt 22, adapted to hold a coverplate 23 in position. 3

The cover plate is provided with a circumferential series of apertures24 coinciding with the safety valve connections 8.

Preferably, the bolt 22 is bored to receive a pin 25 by which a fillingtank 26 may be sup- 9 ported. The filling tank is provided with asuitable flexible connection 27 and valved nozzle (not shown) forfilling the boilers.

According to a modified form the capacity of the gutter may be such thatthe tube 15 is unnecessary and in such case a valved connection may beprovided on the gutter by which the collected water or moisture may bedrained from time to time.

With the form of boiler as descrlbed 1n our .1

companion application in which the valve et is actuated by alongitudinally adjustable rod 4: it may happen that a slight escape ofwater, in the nature of a drop or two, occurs ,when the rod 4 is movedoutwardly. In lorder to catch such drops a drip tray 28 is provided ofannular form which may be se- 1 cured to the periphery of the base ofthe container 9 in any suitable manner such as by screw bolts and nuts.

The drip tray 28 may be utilized for carrying the usual supportingdevices for the steam conveying pipes to the curling means.

e claim:

1. A supporting tray or container for a series of steam boilers for usein connection with hair-waving appliances, wherein means are providedbelow the normal level of the tray for collecting or draining away wateroverflowing from the boilers, or other moisture.

2. A supporting tray or container for a series of steam boilers for usein connection with hair-waving appliances, comprising an annular gutterin the base of the tray and a connection from such gutter to waste.

3. A tray for a series of steam boilers for use in connection withhair-waving appliances, a hollow standard for supporting. the tray, anannular gutter in the base ofthe tray for collecting water overflowingfrom the boilers, or other moisture, and a pipe opening into the gutterand extending into the hollow standard.

4:. A tray for a series of boilers as claimed in claim 3 wherein aremovable waste vessel is mounted at the lower end of the supportingstandard.

5. A supporting tray for a series of steam boilers for use in connectionwith. hair-waving appliances, having a surrounding wall, an annulargutter in the base of the tray and a connection from the gutter towaste, and apertures in the wall and base for accommodating Valveoperating means and downflow tubes of the boilers.

6. A boiler supporting tray as claimed in claim 5 wherein a cover plateis provided having apertures for accommodating safety valve connectionsin the boilers.

7. A boiler supporting tray as claimed in claim 5 wherein a cover plateis provided, a fastening bolt for securing the plate in position, saidbolt having a recess to accommodate a pin adapted to support a vesselfor filling the boilers.

8. A tray as claimed in claim 3 having a surrounding wall, apertures inthe base and wall for accommodating downliow pipes and valve connectionsin the boilers, a cover plate adapted to rest on the boilers and havingapertures accommodating safety valve connections in the boilers, a boltfor securing the cover plate in position, said bolt being bored WILLIAMMACDONALD.
